Three days into the State Fair of Texas, the petting zoo giraffe has returned to its home after some people reported that the animal appeared distressed.

At least two people posted photos and videos to social media showing the giraffe pacing in its enclosure with blood on its body. Some reported that it kept hitting its head.

Stephanie Coon, who posted one video to Facebook, said the giraffe in the Children's Health Barnyard had blood coming out of its nose and mouth and a cut on its chest. Meredith Plunkett said in another Facebook post that a fair representative told her the giraffe was wounded on opening day when it became scared by the fireworks.

Fair spokeswoman Karissa Condoianis said fair officials did not have confirmation about what happened to the giraffe.

"The giraffe was young, and this was its first show," she said. "The environment for this giraffe did not suit its disposition."

Joe Hedrick, operator of the Hedrick's Exotic Animal Farm that has brought animals to the petting zoo for years, already had the giraffe under veterinary supervision, Condoianis said.

He also consulted with three vets, all of whom determined the animal was healthy and could remain at the fair. But on Sunday, Hedrick decided it was best for the giraffe to return to his farm in Kansas, she said.
